Hello

I have yamaha gladiator 125 since 2008.I have run it 62000km.No engine service till today. But i have facing a strange problem.when i start bike it starts smoothly. After running 5-10 km means when its engine warms up then its sound of engine changes. It sounds as its engine is working more. This problem occurs when i press clutch. In neutral or in gear same situation i face. No white smoke.. No black smoke.. I visited yamaha there i was told that may its carburettor is malfunctioning.. Plz help me if anybody can..

Thanks
